Title: Improvements in and relating to the overload protection of electrical energy distributing systems
IPC: H01H71/68
Filed: 1944-02-05
Abstract: 574,597. Protective cut-out arrangements. WHIPP & BOURNE, Ltd., and WHIPP, I. T. L. Feb. 5, 1944, No. 2159. [Class 38 (v)] A circuit-breaker 1, 2 for connecting a supply 3, 4 to a load, is closed by a coil 21 in response to operation of a press-button switch 12, the circuit including a switch arm 13 operated by the breaker 1, 2 and engaging contact 15. When the breaker is fully closed, arm 13 moves to contact 14, so introducing an economy resistance 7 into the holding circuit. An overload coil 9 closes contacts 22 to shortcircuit coil 21 and release the breaker in a time depending on a resistance 8 included in the short-circuit as set forth in Specification 521,073. If, when spark contacts 17, first engage, an overload occurs of sufficient severity to reduce the supply volts to coil 21 and prevent completion of the closing operation, no change-over of switch arm 13 to contact 14 to complete the trip circuit prepared at contacts 22 occurs. An additional contact 16 is therefore provided to open the holding-circuit directly and allow the breaker to open. A no-volt coil 18 is also provided.

Abstract: 773,095. Slewing-]ib cranes. OREBRO BIL- & TRAKTOR AKTIEBOLAG. Jan. 26,1955 [May 14, 1954], No. 2328/55. Class 78 (4). [Also in Group XXI] The pinion 21, Fig. 2, driving the slewing-ring 22 of a crane or excavating machine is driven by a pair of fluid-pressure rams 74, 76 through a crank-pin 72. The fluid-pressure rams are preferably roughly at right-angles and may be connected to the crank-pin 72 by connecting- rods or, as shown, may be directly connected to the crank-pin, the cylinders being mounted by pivoting heads 86, 90 which also serve as valves to control the double-acting rams to provide continuous rotation of the pinion 21 in a direction determined by the connection of conduits 94, 96 forming the supply of pressure fluid and the exhaust. The invention is illustrated as applied to a scoop-arm excavating machine in which an engine 17, Fig. 1, may be connected by coupling-dogs to drive either the rear wheels 15 or a transverse shaft 35 operating a pump supplying pressure liquid to the slewing cylinders 74, 76 and connected by clutches 39 to drive drums 31, 33 operating the cables 23, 25 controlling the excavating apparatus. Each drum 31, 33 is provided with a brake 37.

Abstract: 677,925. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd. Feb. 8, 1951. [Feb. 8, 1950] No. 3252/50. Class 38 (iii). A diesel-electric shunting locomotive of the kind in which an engine - driven direct-current generator supplies a plurality of electric driving motors, has switch means for connecting the motors to the generator either in series or in parallel. As shown, the main enginedriven generator 1 supplies traction motors 2, 3, and has a separately-excited field winding 1a which is energized from a beltdriven auxiliary generator 4. The traction motors are ventilated by a fan 5 mounted on the shaft of the auxiliary generator. For level shunting duties the two motors are connected in parallel across the main generator whilst a variable resistor 12, in circuit with the winding 1a, is short-circuited. For hump shunting duties the traction motors are connected in series and the resistor 12 is connected in circuit with the winding 1a so that the engine has to run at a higher speed to provide the same load current. For the same locomotive speed and tractive effort the load current is reduced compared with that obtained during the parallel-connection so that heating of the generator armature is decreased. The higher speed operation of the engine during the seriesconnection provides increased ventilation of the main generator and traction motors. Interlocks may prevent the change-over from series to parallel whilst power is supplied to the motors. Preferably the excitation of the generator, with the series connection, is such that, with a predetermined maximum generator load current, the engine operates at maximum permitted speed.

Abstract: 902,258. Semi-conductor devices. SIEMENS & HALSKE A.G. Jan. 26, 1960 [Jan. 28, 1959], No. 2820/60. Class 37. A semi-conductor device is made by coating one face of a semi-conductor body with an alloying material, pressing it against a metal support member to bond it thereto and then reducing the thickness of the body. In an embodiment, Fig. 3, the abutting surfaces of a tantalum plate 2 (Fig. 3) and P-type germanium disc 1 are lapped, polished, coated by vapour deposition with aluminium and bonded together by pressure at a temperature above the alloying temperature of germanium and aluminium. The disc 1 is then reduced to a thickness of 10 Á by grinding and/or etching and arsenic diffused into the exposed surface of the disc to form a PN junction therein. In making a transistor (Fig. 4), an N-type disc is used so that bonding to the support also provides a PN junction. After reducing the thickness of the disc an emitter 7 and a ring base contact 8 are alloyed thereto. Alternatively, parallel strip emitter and base electrodes are formed by alloying vapour deposited or dusted on impurity layers to the disc. If an intrinsic wafer is used a PNIP transistor may be formed by first forming an N-type layer 11 (Fig. 5) on the reduced thickness disc by diffusion and subsequently alloying a mass 9 containing a fast diffusing donor and high segregation constant acceptor to the body together with a base ring 8.

Abstract: 801,505. Electromagnetic relays. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 28, 1957 [Jan. 31, 1956], No. 2926/57. Class 38 (5). An arrangement including a D.C. relay which operates when a current or voltage changes suddenly by an amount exceeding a predetermined value or changes by an amount per unit of time which exceeds a predetermined value, comprises, Fig. 1, a normally balanced bridge circuit having resistors 1 ... 4, the resistor 1 being shunted by a condenser 5, so that when there is no change in the supply connected to 6, 7 there is no voltage across the relay winding 10. However, should the supply increase or decrease the condenser 5 will charge or discharge and a voltage arises across the winding to operate the relay. The arrangement may be made to respond to an increase only, or a decrease only by using a polarized relay or by connecting a rectifier in series or in parallel with the relay winding. In a modification (not shown) the relay has two oppositely-acting windings connected in the bridge arms 1, 2. According to the Fig. 2 arrangement which responds only to an increase in the supply the oppositively-acting relay windings 11, 12 are series connected and shunted, respectively, by a resistor 17 and by a resistor 16 and condenser 14 through a rectifier 15. When the condenser is charged upon an increase in the supply a higher voltage arises over the winding 11 than over the winding 12 and the relay operates. In a modification of Fig. 2 (Fig. 3, not shown) a changeover switch is provided permitting the condenser to be replaced by a resistor whereby the arrangement then functions as an overcurrent relay. In the several arrangements the relay may automatically reset but, alternatively, it may be held operated by a self-holding winding.
